[Exploring Needs, Motivations, and Limitations Towards Healthy Eating and Digital Resources: A Qualitative Study in a Mexican Primary Education Setting]. / Exploración de necesidades, motivaciones y limitaciones en relación con la alimentación saludable y recursos digitales: un estudio cualitativo en un entorno de educación primaria en México.

OBJECTIVE: To explore the needs, motivations, and limitations related to healthy eating and digital materials, as well as to identify patterns for their design as a strategy aimed at Mexican families. DESIGN: A qualitative observational study of the phenomenon through focus group sessions. LOCATION: A public primary education center in the city of Querétaro, Mexico. PARTICIPANTS: Children aged 9 to 11 years and parents, mothers, or caregivers with children in primary education. METHOD: Twelve sessions were conducted with three groups of students and two sessions with parents, mothers, or caregivers using an interview guide. Various digital materials, developed based on social cognitive theory, were presented during the sessions. The sessions were recorded with the participants' or their guardians' prior consent and transcribed for analysis. Coding was performed for key points of analysis, and information saturation was confirmed. RESULTS: Students expressed motivation towards digital material that promotes play and experimentation, especially within the family context. The main perceived barrier was the caregivers' resistance to change. Parents expressed motivation and a need for explanatory material on diseases, with economic and time-related barriers. CONCLUSIONS: Digital material based on social cognitive theory, designed to improve nutrition, can be an effective strategy in nutritional education if it considers the circumstances of the target population. It is advisable to include affective and behavioral elements to achieve meaningful learning within households.

Dietary Energy Density Is Associated with Biomarkers of Chronic Diseases-A Cross-Sectional Study of School-Aged Children in Rural Mexico.

Background: Dietary energy density (DED) is associated with chronic disease markers in adults. However, results in children are still controversial. Objective: To evaluate the DED of children and its association with obesity and biomarkers of chronic disease. Methods: In this cross-sectional study, we recruited 284 children (6-10 y) from rural Mexico. Dietary intake was assessed using three 24-h recalls. DED was calculated for "foods only" (DEDfo) and for "foods and beverages" (DEDfb). Weight, height, and body fat percent (dual-energy X-ray absorptiometry) were measured. Inflammatory cytokines, lipid profile, leptin, and insulin resistance were determined from a fasting blood sample. Results: DEDfo was 1.91 ± 0.36 kcal/g and DEDfb was 1.36 ± 0.31 kcal/g. Higher DEDfo and DEDfb were associated with higher risk to have insulin resistance [odds ratio (OR) = 3.92, 95% confidence interval (CI): 1.66, 9.22, P < 0.01; OR = 3.51, 95% CI: 1.25, 9.87, P = 0.02, respectively]. Higher DEDfo was associated with higher risk of higher leptin levels (OR = 3.17, 95% CI: 1.01, 10.23). Also, DEDfo and DEDfb were associated with higher concentrations of cholesterol (ß = 11.67, 95% CI: 1.81, 19.53, P = 0.03; and ß = 11.74, 95% CI: 2.69, 20.74 P = 0.01, respectively) and higher odds of having high insulin concentrations (OR = 2.52, 95% CI: 1.26, 5.06, P = 0.01; and OR = 2.95, 95% CI: 1.30, 6.70, P = 0.01). DEDfo and DEDfb were not associated with any measure of obesity and inflammatory cytokines in the adjusted models. Conclusions: DED was associated with higher leptin and cholesterol concentrations, and having insulin resistance, but not with any measure of obesity or inflammation. Reducing DED may reduce risk of cardiovascular disease and improve insulin sensitivity in school-aged children.

The ERA Registry Annual Report 2020: a summary.

Background: The European Renal Association (ERA) Registry collects data on kidney replacement therapy (KRT) in patients with ESKD. This paper is a summary of the ERA Registry Annual Report 2020, also including comparisons among primary renal disease (PRD) groups. Methods: Data were collected from 52 national and regional registries from 34 European countries and countries bordering the Mediterranean Sea: 35 registries from 18 countries providing individual level data and 17 registries from 17 countries providing aggregated data. Using this data, KRT incidence and prevalence, kidney transplantation rates, expected remaining lifetimes and survival probabilities were calculated. Results: A general population of 654.9 million people was covered by the ERA Registry in 2020. The overall incidence of KRT was 128 per million population (p.m.p.). In incident KRT patients, 54% were older than 65 years, 63% were men and the most common PRD was diabetes mellitus (21%). Regarding initial treatment modality in incident patients, 85% received haemodialysis (HD), 11% received peritoneal dialysis (PD) and 4% received a pre-emptive kidney transplant. On 31 December 2020, the prevalence of KRT was 931 p.m.p. In prevalent patients, 45% were older than 65 years, 60% were men and glomerulonephritis was the most common PRD (18%). Of these patients, 58% were on HD, 5% on PD and 37% were living with a kidney transplant. The overall kidney transplantation rate in 2020 was 28 p.m.p., with a majority of kidney grafts from deceased donors (71%). The unadjusted 5-year survival, based on incident dialysis patient from 2011-15, was 41.8%. For patients having received a deceased donor transplant, the unadjusted 5-year survival probability was 86.2% and for patients having received a living donor transplant it was 94.4%. When comparing data by PRD group, differences were found regarding the distribution of age groups, sex and treatment modality received.

Persistently elevated serum concentrations of human chorionic gonadotropin (hCG).

OBJECTIVES: We describe a woman with constantly elevated hCG levels in serum. Since assay interference, pregnancy or cancer did not explain the elevated levels, we measured the concentrations of hCG, its ß subunit (hCGß) and its core fragment (hCGßcf) in serum and urine using specific assays, to understand the nature of the elevated hCG levels. METHODS: We used 3 assays for total hCG (these assays also recognize hCGß and to various degrees hCGßcf), 3 for intact hCG heterodimer, 3 for free hCGß and one for hCGßcf. RESULTS: With an hCG assay detecting total hCG the serum concentrations were in the range of 150-260 IU/L for the whole study period of almost 5 years, except for a peak of 1,200 IU/L, coinciding with a spontaneous abortion. Quantitation of different forms of hCG with specific immunoassays showed that the immunoreactivity in serum consisted of hCGß. Urine contained hCGß and hCGßcf. CONCLUSIONS: The laboratory findings are in keeping with familial hCG syndrome. However, so far the condition remains to be determined in any family members. Elevated hCG levels without any explanation are problematic as they cause suspicion of cancer or ectopic pregnancy and may lead to harmful therapy. Specific assays, as used here, will aid in diagnosis of such cases.

Food insecurity is associated with glycemic markers, and socioeconomic status and low-cost diets are associated with lipid metabolism in Mexican mothers.

The association between socioeconomic status (SES) and chronic disease has recently become more evident in middle- and low-income countries. We hypothesized that poor socioeconomic conditions, such as food insecurity, low educational level, or low SES, may restrict access to a healthy diet and may be associated with cardiometabolic risk independently of body fat. This study examined the relation between socioeconomic indicators, body fat, and cardiometabolic disease risk markers in a random sample of mothers living in Queretaro, Mexico. Young and middle-aged mothers (n = 321) answered validated questionnaires to determine SES, food insecurity, and educational level and a semiquantitative food frequency questionnaire to determine dietary patterns and the cost of individual diet. Clinical measurements included anthropometry, blood pressure, lipids profile, glucose, and insulin. Obesity was present in 29% of the participants. Women with moderate food insecurity had higher waist circumference, glucose, insulin, and homeostasis model assessment of insulin resistance than women with food security. High triglyceride concentration and lower levels of high-density lipoprotein and low-density lipoprotein cholesterol were associated with lower SES and lower educational level. Women who consumed a lower carbohydrate diet had higher SES, higher education, and better cardiovascular risk markers. The higher carbohydrate diet profile was the least expensive diet. There was an inverse association between the cost and energy-density of foods. In conclusion, food insecurity was associated with glycemic control markers, and lower SES and education were related to a low-cost, higher carbohydrate diet and to a greater cardiovascular risk. The influence of the social environment on obesity and cardiovascular diseases needs to be further explored.

Design and Validation of a Food Frequency Questionnaire to Evaluate the Consumption of Trans Fatty Acids in the Adult Population (FFQ-TFA).

Instruments for estimating the intake of food components can be useful in the prevention and/or treatment of diseases related to improper diet. There is, at present, no scientifically validated instrument for estimating consumption of trans fatty acids (TFA) in the Mexican population. The objective of this study was to design and validate such an instrument: a questionnaire that can be used to estimate consumption of TFA from food products. The questionnaire was applied to 162 students from the Autonomous University of Querétaro (UAQ). There were two phases to the study: (1) design of a food frequency questionnaire to assess consumption of trans fatty acids (FFQ-TFA) and an eating practices questionnaire (EPQ-TFA); (2) validation of the instrument. Content validity was measured by expert review and by Aiken's V method, obtaining an overall score of 0.895. As final tests for the FFQ-TFA analysis, criterion validity was measured using Spearman's correlation (r = 0.717, p < 0.01) and a linear regression (B = 0.668), considering the results of the 24-h dietary recall (24 HR); and reproducibility or temporal stability was measured using Pearson's correlation (r = 0.406, p < 0.01). Subsequently, a Pearson correlation was applied between TFA consumption estimated by the FFQ-TFA-2 and the global score from the EPQ-TFA-2 (r = 0.351, p < 0.01). A Pearson correlation was applied between the EPQ-TFA-1 and the EPQ-TFA-2 (r = 0.575, p < 0.01). TFA consumption per day was 2.49 ± 1.32 g in the participating population, which was 1.04 ± 0.51% of their total kcal consumption.

Content of industrially produced trans fatty acids in breast milk: An observational study.

Breast milk may contain industrially produced trans fatty acids (TFAs), which can affect the content of essential fatty acids (EFAs). This could have significant implications for the child's development. The fatty acids present in breast milk can be modified by adjusting the mother's diet. The objective of this study was to determine the content of industrially produced TFAs present in colostrum, transitional milk, and mature milk produced by mothers between 18 and 45 years of age in the state of Querétaro, Mexico, based on a longitudinal observational study. The TFA content in the breast milk of 33 lactating women was analyzed using gas chromatography. The mothers' consumption of TFAs was also estimated by analyzing a log prepared through 24-hr dietary recall (24HR) obtained in each period. The TFA content in the mothers' diet was similar across the colostrum, transitional milk, and mature milk phases: 1.64 ± 1.25 g, 1.39 ± 1.01, and 1.66 ± 1.13 g, respectively. The total TFA content was 1.529% ± 1.648% for colostrum; 0.748% ± 1.033% for transitional milk and 0.945% ± 1.368% for mature milk. Elaidic acid was the TFA in the highest concentration in all three types of milk. No correlation was found between the content of industrially produced TFAs in breast milk and the anthropometric measurements of the mother or between the estimated consumption of TFAs and the content of TFAs in breast milk. Elaidic acid and total content of TFAs were negatively correlated (p < .05) with the content of docosahexaenoic acid (DHA) (0.394 ± 0.247) (R = -0.382) in colostrum. The concentration of TFAs was found to correlate with the composition of EFAs in milk.

Differences in the Clinical Profile and Management of Atrial Fibrillation According to Gender. Results of the REgistro GallEgo Intercéntrico de Fibrilación Auricular (REGUEIFA) Trial.

To analyze the clinical profile and therapeutic strategy in atrial fibrillation (AF) according to gender in a contemporaneous patient cohort a prospective, multicenter observational study was performed on consecutive patients diagnosed with AF and assessed by cardiology units in the region of Galicia (Spain). A total of 1007 patients were included, of which 32.3% were women. The mean age of the women was significantly greater than that of the men (71.6 versus 65.7 years; p < 0.001), with a higher prevalence of hypertension (HTN) and valve disease. Women more often reported symptoms related to arrhythmia (28.2% in EHRA class I versus 36.4% in men), with a poorer level of symptoms (EHRA classes IIb and III). Thromboembolic risk was significantly higher among women (CHA2DS2-VASc 3 ± 1.3 versus 2 ± 1.5), in the same way as bleeding risk (HAS-BLED 0.83 ± 0.78 versus 0.64 ± 0.78) (p < 0.001), and women more often received anticoagulation therapy (94.1% versus 87.6%; p = 0.001). Rhythm control strategies proved significantly less frequent in women (55.8% versus 66.6%; p = 0.001), with a lesser electrical cardioversion (ECV) rate (18.4% versus 27.3%; p = 0.002). Perceived health status was poorer in women. Women were older and presented greater comorbidity than men, with a greater thromboembolic and bleeding risk. Likewise, rhythm control strategies were less frequent than in men, despite the fact that women had poorer perceived quality of life and were more symptomatic.

Patients and relatives as auditors of safe practices in oncology and hematology day hospitals.

BACKGROUND: When there is a gap in professionals' adherence to safe practices during cancer treatment, the consequences can be serious. Identifying these gaps in order to enable improvements in patient safety can be a challenge. This study aimed to assess if cancer patients and their relatives can be given the skills to audit reliably four safe practices, and to explore whether they are willing to play this new role. METHODS: We recruited 136 participants in 2018, from the oncology and haematology day hospital of a tertiary hospital in Spain. Patient identification, hand hygiene, blood or chemotherapy identification, and side effects related to transfusion and chemotherapy, were the safe practices selected for evaluation. The study comprised two parts: an interventional educational program and a cross-sectional design to collect data and assess to what degree participants are able and willing to be auditors depending on their characteristics using multivariate logistic regression models. A participant's auditing skill were assessed pre and post the educational intervention. RESULTS: The model was seeking predictors of being a good auditor. 63 participants (46.3%) were classified as good auditors after the training. To have younger age, higher educational level and to have had an experience of an adverse event were associated with a higher probability of being a good auditor. Additionally, 106 (77.9%) participants said that they would like to audit anonymously the professionals' compliance of at least three of four safe practices. The willingness to audit safe practices differed depending on the safe practice but these differences did not reach statistical significance. CONCLUSIONS: The data gathered by patients and relatives acting as auditors can provide healthcare organizations with valuable information about safety and quality of care that is not accessible otherwise. This new role provides an innovative way to engage patients and their families' in healthcare safety where other methods have not had success. The paper sets out the methods that healthcare organizations need to undertake to enrol and train patients and relatives in an auditor role.

Effect of the application of the "Patient blood management" programme on the approach to elective hip and knee arthroplasties. / Efecto de la aplicación del programa Patient blood management en el abordaje de las artroplastias de cadera y rodilla programada.

BACKGROUND AND OBJECTIVES: The "Patient Blood Management" (PBM) programmes have demonstrated their value in the continuous improvement of care practice, due to continuous systematic reviewing of results and their dynamic and multidisciplinary updating in accordance with new clinical evidence. Our goal is to demonstrate the effectiveness of simple protocols, applicable in second level hospitals. PATIENTS AND METHODS: 702 patients undergoing scheduled arthroplasty from 2011 to 2018 were retrospectively analysed. During this period, the evolution of transfusion rates and anaemia and bleeding management were recorded in the patients' computerised clinical histories. RESULTS: Stages and transfusion rates were: Year 2011-2012, "Universal self-donation programme": 62.4%; year 2013, "Optimization of preoperative haemoglobin and universal self-donation withdrawal", 22.5%; year 2015, "Stopping the use of cell-savers and drains", 13.2%; and year 2017, "Introduction of routine tranexamic acid", 3.6%. A significant reduction in the transfusion rate and volume (P<.001) and the average hospital stay (8 to 6 days) (P<.001) was achieved. In multivariate models, transfused patients have a .5-day stay and there is a trend towards a reduction in complications, being fewer in patients receiving tranexamic acid (OR .44). CONCLUSION: A simple progressive and multidisciplinary PBM programme, with continued re-evaluation, has allowed a reduction in transfusion rates and average hospital stay.

Gut Bacterial Families Are Associated with Body Composition and Metabolic Risk Markers in School-Aged Children in Rural Mexico.

Background: Differences in gut microbiota composition have been associated with obesity and metabolic alterations in children. The aim of this study was to analyze the abundance of the main bacterial families of the gut among children according to their body composition and metabolic markers. Methods: A cross-sectional study was conducted with 93 school-aged children (8.4 ± 1.6 years old). Anthropometric and body composition variables were measured and a blood sample was collected to determine glucose, insulin, lipid profile, C-reactive protein, leptin, and cytokines [interleukin 6, interleukin 10 (IL-10), tumor necrosis factor α (TNFα)]. DNA was extracted from stool samples and the abundance of bacterial families (Bacteroidaceae-Porphyromonadaceae-Prevotellaceae, Lactobacillaceae, Enterococcaceae, and Lachnospiraceae-Ruminococcaceae) was determined by qPCR assays. Results: Children with obesity and high waist/height ratio had lower Bacteroidaceae-Porphyromonadaceae-Prevotellaceae and higher abundance of Lactobacillaceae when compared with normal-weight children. TNFα was negatively associated and IL-10 was positively associated with Bacteroidaceae-Porphyromonadaceae-Prevotellaceae. Triglycerides showed a positive relationship with Lachnospiraceae-Ruminococcaceae whereas high-density lipoprotein-cholesterol was negatively associated with Lactobacillaceae. Conclusion: In rural Mexican school-aged children, a low abundance of Bacteroidaceae-Porphyromonadaceae-Prevotellaceae and a high abundance of Lactobacillaceae are associated with obesity and metabolic disturbances.

Prognostic Value of Late Gadolinium Enhancement for the Prediction of Cardiovascular Outcomes in Dilated Cardiomyopathy: An International, Multi-Institutional Study of the MINICOR Group.

BACKGROUND: Dilated cardiomyopathy is associated with increased risk of major cardiovascular events. Late gadolinium enhancement (LGE) cardiac magnetic resonance imaging is a unique tissue-based marker that, in single-center studies, suggests strong prognostic value. We retrospectively studied associations between LGE presence and adverse cardiovascular events in patients with dilated cardiomyopathy in a multicenter setting as part of an emerging global consortium (MINICOR [Multi-Modal International Cardiovascular Outcomes Registry]). METHODS: Consecutive patients with dilated cardiomyopathy referred for cardiac magnetic resonance (2000-2017) at 12 institutions in 4 countries were studied. Using multivariable Cox proportional hazard and semiparametric Fine and Gray models, we evaluated the association between LGE and the composite primary end point of all-cause mortality, heart transplantation, or left ventricular assist device implant and a secondary arrhythmic end point of sudden cardiac death or appropriate implantable cardioverter-defibrillator shock. RESULTS: We studied 1672 patients, mean age 56±14 years (29% female), left ventricular ejection fraction 33±11%, and 25% having New York Heart Association class III to IV; 650 patients (39%) had LGE. During 2.3 years (interquartile range, 1.0-4.3) follow-up, 160 patients experienced the primary end point, and 88 experienced the arrhythmic end point. In multivariable analyses, LGE was associated with 1.5-fold (hazard ratio, 1.45 [95% CI, 1.03-2.04]) risk of the primary end point and 1.8-fold (hazard ratio, 1.82 [95% CI, 1.20-3.06]) risk of the arrhythmic end point. Primary end point risk was increased in patients with multiple LGE patterns, although arrhythmic risk was higher among patients receiving primary prevention implantable cardioverter-defibrillator and widening QRS. CONCLUSIONS: In this large multinational study of patients with dilated cardiomyopathy, the presence of LGE showed strong prognostic value for identification of high-risk patients. Randomized controlled trials evaluating LGE-based care management strategies are warranted.

Transfusion of D positive red cells to selected D-negative patients. / Transfusión de hematíes D positivo a pacientes seleccionados D negativo.

BACKGROUND: To transfuse packed red blood cells isogroup ABO D is a usual transfusion practice. However, when there is not enough D negative blood available, we can transfuse positive red blood cells to negative patients. Immunocompetent D negative individuals may develop serologically detectable anti-D antibodies within 3 months after exposure to D positive red blood cells. MATERIAL AND METHOD: Over the last 18 years, we have experienced situations of D negative blood cell scarcity. In these situations, we have applied a clinical assistance protocol, selecting patients with lower risk of alloimmunization and chronic transfusion requirements. We have retrospectively evaluated this policy for the use of D positive red blood cells in D negative patients, focussing on alloinmunization and mortality. RESULTS: Applying the protocol, 3% of D negative patients were transfused with D positive units, with an alloimmunization rate of 12.3%. The rate of alloimmunization was higher in the younger age group and in those transfused with more units. No haemolytic reactions were reported. Mortality in the alloimmunized group was lower. CONCLUSION: The use of D positive red blood cells in selected D negative patients does not induce adverse reactions, is a safe practice and allows saving of a product that is sometimes limited.

Overvaluation of Eating and Satiation Explains the Association of Food Insecurity and Food Intake With Obesity and Cardiometabolic Diseases.

BACKGROUND: In developing countries, where energy-dense foods with low nutrient content are highly accessible, the fear of feeling hungry and the desire of prolonging satiation have been documented. OBJECTIVE: To evaluate the role of valuation of eating and satiation in the relationship of food insecurity with diet, obesity, and cardiometabolic risk with structural equation modeling. METHODS: A validated questionnaire that measures the value of eating and satiation (VES) as the basis of wealth was administered to 321 adult women from Queretaro, Mexico. Instruments for measurement of socioeconomic status, food insecurity, physical activity, and a semiquantitative food frequency questionnaire were also applied. Women were measured and weighed, and they provided a fasting blood sample to determine lipid profile, glucose, and insulin concentrations. Structural equation models were used for prediction of the homeostasis model assessment-insulin resistance (HOMA-IR) index and triglyceride/high-density lipoprotein (HDL) cholesterol index. RESULTS: The models confirmed, with acceptable goodness-of-fit parameters, the mediation position of VES between past experiences of food insecurity and a greater intake of carbohydrates and its impact on obesity, and on the HOMA-IR and the triglyceride/HDL-cholesterol index. CONCLUSION: Experiences of food insecurity may increase VES in women and influence eating behavior, increasing intake of sugars and starches in their diet, thus increasing the risk of obesity and cardiometabolic diseases such as diabetes. The understanding of essential values that induce unfavorable eating behavior in a population that has experienced past food insecurity may help to develop public health strategies for prevention of cardiometabolic diseases.

Lower Protein Intake Supports Normal Growth of Full-Term Infants Fed Formula: A Randomized Controlled Trial.

Infant formulas have been conventionally prepared with an excess of total protein in order to provide sufficient amounts of essential amino acids to the rapidly growing infant. However, this practice leads to higher than necessary protein intake during early infant development, inducing accelerated growth patterns correlated with the development of chronic diseases later in life. This study was aimed at assessing the safety of an infant formula enriched with bovine alpha-lactalbumin containing a total protein concentration very close to that of human milk, and determining its efficacy in the support of healthy infant growth from the first month to the fourth month of age. Healthy full-term infants ≤40 days of age were randomized in this controlled single blind trial to one of the following infant formulas: IF 1 (containing 1.0 g protein/dL; n = 30), IF 2 (containing 1.3 g protein/dL; n = 24), and IF 3 (containing 1.5 g protein/dL; n = 42). A control group consisting of exclusively breastfed infants (HM; n = 212) was included in the study. Anthropometric measurements and Z-scores were evaluated at baseline, at 1 month of age, and at 4 months of age. Weight gain (g/day) was similar in the IF 1 and the HM groups (p = 0.644), and it was significantly greater in the IF 2 and IF 3 groups than in the HM group. Growth patterns in both breastfed or IF-fed infants were in accordance with the World Health Organization (WHO) growth standards. At four months of age, the mean weight-for-age Z-score (WAZ) adjusted for initial value in the IF 1 group was similar to that of the HM group and significantly lower than that of the IF 2 and IF 3 groups (p = 0.031 and p = 0.014 for IF 2 and IF 3, respectively). Length-for-age (LAZ) adjusted for initial value was similar among all groups at four months of age. From 1 to 4 months of life, IF 1 containing 1.0 g protein/dL promotes growth and weight gain similar to those observed in exclusively breastfed infants. As this is a first approach to studying an IF containing total protein in a level below that recommended by international committees on nutrition, further investigations are needed to support these findings evaluating infant’s metabolic profile and growth in the long term.

Desarrollo y validación de escalas para medir el valor que las mujeres dan a la saciedad y a la alimentación: un factor crítico para el tratamiento de la obesidad / Development and validation of scales to measure women's eating and satiation values: a criti- cal factor in the treatment of obesity

La sobrevaloración de la alimentación y de la saciedad en familias que viven en un medio influenciado por la globalización y desarrollo de la industria alimentaria, puede estar teniendo un efecto sinérgico en el desarrollo de la obesidad y sus comorbilidades en países de ingreso medio. El objetivo de este trabajo fue desarrollar y validar escalas para medir el valor otorgado a la alimentación y la saciedad en mujeres. Se desarrolló un instrumento y se aplicó en querétaro, México (n=243), se midieron variables socioeconómicas y de percepción de peso corporal. Se realizó análisis factorial explorato- rio, confirmatorio y ANOVA. Las escalas del valor que las mujeres dan a la alimentación como base del bienestar, a la saciedad y a la alimentación como base del bienestar del hijo, se validaron (α-Cronbach>0.66) y se confirmaron (CFI>0.98;RMSEA<0.05). Los puntajes de valor de la alimentación y de la saciedad se asociaron con un menor nivel socioeconómico y educativo, inseguridad alimentaria en el pasado, menor intención de perder peso y con percepción bajo peso en los hijos. En conclusión, las es- calas para medir el valor de la alimentación y la saciedad tienen validez para ser utilizadas en futuros estudios; su utilización puede contribuir a desarrollar estrategias que consideren la verdadera motivación de la alimentación en los segmentos poblacionales más desfavorecidos(AU)

The overvaluation of eating and satiation in families whose environment has been influenced by globalization and the food industry, could be inducing obesity and its co-morbidities in midd- le income countries. The objective was to develop and validate scales to measure women's eating and satiation values. A measurement instrument was developed and ad- ministered to women from querétaro, Mexico (n=243), it also measured socioeconomic (SE) and body weight per- ception variables. Analyses included exploratory and con- firmatory factorial analyses and ANOVA. The scales that represented the value of feeding as basis of wealth, the va- lue of satiation and the value of feeding a child as the basis of the child's wealth, were validated (Cronbach-α>0.66) and confirmed (CFI >0.98; RMSEA<0.05).The scores were associated with a lower SE status, lower education level, childhood food insecurity, low intention to lose weight and with an underweighted child perception. In conclusion, the scales that measure the value of eating and satiation have the validity to be used in future studies; its utilization can contribute to develop strategies to improve eating behavior of underprivileged population segments, that take into consideration the real motives of eating(AU)
